THRESHING-MACHINE.

Specification of Letters Patent.

Application filed April 18, 1912. Serial No. 691,556.

To all whom it may concern:

Be it known that I, GEORGES ERHARD MARIE GUY BERNARD DE SALABERRY, a citizen of the Republic of France, residing in Foss, Loir-et-Cher, France, have invented new and useful Improvements in Threshing- Machines, which improvements are fully set forth in the following specification.

Different forms of threshing machines are known, which, after'the grain has been threshed out, permit of the immediate separation of the grains and the stalks. One of these devices in particular is characterized by the employment of a rotary heater and a counter beater arranged eitherperpendicularly to the tractor device and striking the cereals perpendicularly to the stalks in the portion not seized by the chains of the said tractor or parallel with the tractor device and seizing the cereals-throughout the entire length of their stalks. This rotary beater can be utilized either with a view to complete threshing or for completing the work of threshing by combs.

The present invention relates to a form of the machine in which the total threshing is insured by means of a double rotary beater. This system of double rotary threshing is represented by way of example in the accompanying drawing, in which the shafts of the heaters are arranged parallel with the tractor device although it should be understood that these shafts might equally well be arranged perpendicularly to the said de- 5 vice.

Figure 1 is a perspective view of the machine. Fig. 2 is a cross section of the beater system. Figs. 3 and 4 relate to details of the beater bars and Fig. 5 is a section of a modified construction of the beater-bars.

The primary heater is formed ofbars 2 which may be of wood, metal or any other appropriate material carried by arms 3 radiating from a shaft 4 parallel with the tractor l, in thecase represented is combined with a second beater analogous to the first,

the shaft 4: of which is parallel with the shaft 4. The shaftsi, 4 are supported in suitable hearings of the thresher-frame and an appropriate transmission'connects directly or indirectly saidshafts with the'drivtion of the two heaters. The interval between the shafts 4: and 4is such that the corresponding bars2 2 of the two devices pass as close as possible to each other.

ing axle and produces a movement of rota- Instead of making the two heaters openwork, they might be solid in which case the bars 2 2' are united by sheets of metal to prevent the choking which might occur in open-work heaters as shown in Fig. 5.

The counter heater or breasting 5 is to some extent common to the two heaters This counter beater may be formed of gratings, iron rods or wooden bars composing an openwork surface suitable both for the threshing and for the escape of the threshed grains or it may be constituted by bars, blades or rods 6 arranged parallel (in the case here illustrated) or perpendicularly (or else parallel and perpendicularly) to the shafts 4:, 4 furnishing an openwork surface. In any case the openwork surface can be curved almost to the junction with the bars 2, 2 of the two heaters or they may not be curved or be curved in an intermediate manner. I V

The bars, blades or rods of the counterheater are fixed and rigid, so that the space separating them from the heaters is constant, or mounted on links, slides or otherwise, so that said space may vary according to the greater or less thickness of the layer of stalks to be submitted into the beater device. The counter beater may also be provided with salient portions which facilitate the threshing. p

The tractor may he composed either of aprons constituted by chains, cables or endless belts or of endless sheets.

In any case the stalks of the cut cereals I completed from 7 to 7 by the action of the bars 2 of this second beater and of the bars 6 of the counter beater. At 7 the stalks; are again seized by the bars 2 of the first beater and carried toward the outlet from the beater system after having experienced a secondary supplementary threshing which removes from the cereals any grains that rods' 'radiating from the ends of said'shafts, 'and'bars connecting said rods-to formrotary beatersonqsaid shafts, and a'countermay have remained in them. The straw escapes from thebeater? system as indicated by the arrow 9 (Fig; e;

A'boX or drum 10 0f suitable form surrounding the beater system: collects the grains whenthey leave the breasting. The discharge of the grains from this drum is effected either'throughanaperture 11 (Fig.

2) arranged at'its lowestfpart or naturally at the lower edge. I I

It hasalreadybeen stated that the bars 2 and 2 of the tworotarybeaters almostfcon tact on their'passa'ge as indicated in Fig. 3;

In order toprevent the stalks from having a tendency at 7; I to enter "the interval then formed between the bars, these bars 2 and 2 may be crenelated as shown in Fig. 4.

V The same result can also-be obtained when the bars of the two beatersall but come into contact, either by imparting a more rapid movement of rotation toone of the appara tus or by providing the second beater with 1 bars presentlng a rougher surface which give it a better hold onthestraw and prevent it from being carried along by the first apparatus. Finally, it. should be noted that the threshing apparatus can be rendered operative independently. of any animal or me chanical traction of the harvester by a motor of any kind'arranged on the machine. This motor may itself actuate the. blades, the endless aprons and the ;.entire mechanism threshing apparatus, thetraveling over the field. and the operation of the parts not actuated byv this motor being reserved for the animal or mechanical traction." r

In practice the, lower part of the'counter beater might be omitted, its purpose being to complete the threshing of the, grain and the cleaningof the stalks by a shaker permitting of obtaining the same result.

The shaker can be'constituted-by-rods,

i. bars, strips or the like to which a crank shaft or cams impart a reciprocating movement which serves to facllltatethe discharge,

of the stalks separated from the grain while at the same time freeing them from any grains that may still adhereto them. Similarly metal rods might be substituted for this 'shaker, these rods being given a vibratory movement by the. operation of the ma- I chine itself and presenting an inclined plane for thestalks -might suffice for their discharge. The grain also passes through a beater coacting with said rotary heaters, eX-

tending along the upper side of the said.

rotary beaters, over the outer end, and along the underside thereof, following the path of the cereal along said boaters, forthe purpose of effectinga complete separation of the grain from the stalks, and. meansfor.

feeding the cereal to the said heaters.
